SpeechRecognizer |什么都没发生什么事(发生什么事)?

我在Google上找不到答案,或者我找不到正确的答案。

所以SpeechRecognizer工作正常。 但是当我听到哔哔声(我在没有谷歌对话框的情况下使用它)并且我在3秒或更长时间内没有说什么时,它就像识别器什么都不做而消失,没有第二次发出哔哔声,没有onResult(),没有EndofSpeech。

那么当识别器正在聆听并且您什么都不说时会发生什么?哪种方法被解雇了?

编辑:毕竟它有效,非常感谢OpiateFuchs和他真正的好评和答案。我编辑简化代码的方式,你们可以看到如何制作它 即使你什么也没说,onPartialResult()经常被调用,但是当发生这种情况时,partialResult字符串是空的,所以如果它是空的,你就知道什么都没说。 (来自OpiateFuchs的想法)

这是我对识别器很重要的简化代码:

public Constructor (){
        speech = SpeechRecognizer.createSpeechRecognizer(context);
        speech.setRecognitionListener(this);
        recogIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        recogIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "de");
        speech.startListening();
}

public void startListening(){
    speech.startListening(recogIntent);
    if(timerRunning==false){
        setcdt();
        mCountDownTimer.start();
        timerRunning=true;
    }
}

@Override
public void onReadyForSpeech(Bundle params) {

}

@Override
public void onBeginningOfSpeech() {

}

@Override
public void onRmsChanged(float rmsdB) {

}

@Override
public void onBufferReceived(byte[] buffer) {

}

@Override
public void onEndOfSpeech() {
    Toast.makeText(c, "work", Toast.LENGTH_SHORT);
    //too see if its called
}

@Override
public void onError(int error) {

}

@Override
public void onResults(Bundle results) {
    ArrayList<String> matches = results
            .getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);

    Toast.makeText(c, matches.get(0), Toast.LENGTH_LONG).show();
    speech.cancel();
    analyse(matches.get(0));
    m.next(); //calls the Recognizer again

}

@Override
public void onPartialResults(Bundle partialResults) {
ArrayList<String> matches = partialResults
            .getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);

    if(matches.get(0).length() == 0){
        m.tv.append("nothing"); //show on textview

    }
    else{
        m.tv.append("cancel timer "); //show on textview
        mCountDownTimer.cancel();
        hasSpoken = true;
        timerRunning = false;
    }

}

@Override
public void onEvent(int eventType, Bundle params) {

}

//innerclass
public class FinishSpeechRecognizerTimer extends CountDownTimer {

    public FinishSpeechRecognizerTimer(long startTime, long interval){
        super(startTime,interval);

    }

    @Override
    public void onFinish(){
        timerRunning = false;
        if (hasSpoken==false){
            m.tv.append("nospeak ");
            speech.cancel();
            m.tv.append("listen again after no speak ");
            startListening();
        }
    }

    @Override
    public void onTick(long millisUntilFinish){

    }
}

public void setcdt(){
    startTime = 5000;
    interval = 4000; //want no onTick - interval > startTime
    timerRunning = false;
    hasSpoken = false;
    mCountDownTimer = new FinishSpeechRecognizerTimer(startTime, interval);
}

答案 0 :(得分:1)

对于这个讨论,我尝试从头开始提供一个示例,它将引导您进入正确的方向。正如评论中所述,如果没有任何内容,SpeechRecognition似乎不会自行停止,所以您只需implement CountDownTimer例如SpeechRecognizer完成SpeechRecognizer过了一段时间后:

制作全球boolean(与您一样),CountdownTimerobjects private SpeechRecognizer speech; private boolean hasSpoken=false; private CountDownTimer mCountDownTimer; private long startTime = 30000L; private long interval = 1000L; private boolean timerRunning = false;

CountDownTimer class

扩展public class FinishSpeechRecognizerTimer extends CountDownTimer{ public FinishSpeechRecognizerTimer(long startTime, long interval){ super(startTime,interval); } @Override public void onFinish(){ if(hasSpoken==false){ speech.cancel(); } timerRunning=false; } @Override public void onTick(long millisUntilFinish){ //do whatever you want to do } }

speech = SpeechRecognizer.createSpeechRecognizer(yourContext);
mCountDownTimer = new FinishSpeechRecognizerTimer(startTime, interval);

<强>初始化

CountDownTimer

启动它,同时启动speech.startListening(recogIntent); if(timerRunning==false){ mCountDownTimer.start(); timerRunning=true; }

boolean value

一旦说出某些内容,请将hasSpoken true设置为cancel@Override public void onBeginningOfSpeech() { hasSpoken=true; mCountDownTimer.cancel(); timerRunning=false; } 计时器:

CountDownTimer

正如我所说,从头开始,无法保证这是有效的。此示例启动onBeginOfSpeech() 30秒,并检查是否有内容。你想等多久取决于你。

修改

事实证明,在某些情况下,onBeginOfSpeech()方法被多次调用,而没有任何人在说话。对于所有感兴趣的人:

而不是在onPartialResult():中执行此操作,您可以使用方法@Override public void onPartialResults(Bundle partialResults) { ArrayList<String> matches = results .getStringArrayList(SpeechRecognizer.RESULT_RECOGNITION); if(matches.size()==0){ hasSpoken=false; }else{ hasSpoken=true; mCountDownTimer.cancel(); timerRunning=false; } }
